I have a midwife and her assistant, and I'm planning a kind-of UC. Basically, I'm going to labor alone for most of the time, then call her. Ideally, they'll be in the other room when I give birth. Actually, the closer I get to that time, the more I become comfortable with totally UCing, but we'll see how I feel at the time. I think more than anything, they'll be able to help my dh through it!
She's really, super laid back and natural, so my appointments don't even feel like appointments. She doesn't weigh me, and has made me feel so much better about my slow weight gain. (Unlike the midwives I had with my dd who freaked me out and talked me into sonograms.) They just check my bp, and we listen to the baby with a fetoscope. Then we spend the rest of the time just talking, not even always about the pregnancy, just chit chat. It's nice to just get to know them as people, that way if I do need them when I'm in labor, I'll trust them more. I would certainly never-ever go back to a more medically inclined midwife. Might as well have had a doctor! If I have any more, I'm going totally UP and UC.
